The two way front vented system encompasses the same design technology of the DM550 with its rigid one-piece baffle construction, but offers a noticeable extended bass – thanks to a bigger 8in bass/midrange driver and increased enclosure size. Technical highlights ● B&W's Tweeter technology ensures that the sound remains focused and time sensitive and that the stereo image is presented with unparalleled three dimensional accuracy. ● The cabinets feature a specially designed high density front baffle which achieves almost Matrix-like stability in strengthening overall enclosure construction. The bevel edges of the front moulding reduce diffraction and improve dispersion. ● The crossover components use heavy gauge wire throughout and new drivers guarantee not only high reliability but ensure that top specifications are met.
